Abstract (en)
[origin: WO2006087661A1] An illumination system, comprising a radiation source and a luminescent material comprising at least one phosphor capable of absorbing a part of light emitted by the radiation source and emitting light of wavelength different from that of the absorbed light; wherein said at least one phosphor is a yellow red-emitting cerium(III)- activated alkaline earth oxonitridoaluminosilicate of general formula Ca1-x-yAxAl1+a- bBbSi1-aN3-aOa:Cey, wherein A selected from the group comprising beryllium, magnesium, strontium, barium, zinc, manganese, lithium, sodium, potassium, rubidium, praseodymium, samarium, europium, and B selected from the group comprising boron, gallium, scandium and wherein 0 < x = l; 0 < y < 0.2; 0.001 < a < 1 and 0.001 < b < 1 can provide light sources having high luminosity and color-rendering index, especially in conjunction with a light emitting diode as a radiation source. The red to yellow -emitting cerium(III)-activated alkaline earth oxonitridoaluminosilicate of general formula Ca1-x-yAxAl1+a-bBbSi1-aN3-aOa:Cey, wherein A selected from the group comprising beryllium, magnesium, strontium, barium, zinc, manganese, lithium, sodium, potassium, rubidium, praseodymium, samarium, europium, and B selected from the group comprising boron, gallium, scandium and wherein 0 < x = l; 0 < y < 0.2; 0.001 < a < 1 and 0.001 < b < 1 is efficiently excitable by primary radiation in the near UV-to-blue range of the electromagnetic spectrum.
